The tribunal ruled Mr Montalto exploited the power imbalance with his students at a university in Melbourne, which can't be named, between June and August 2014 when he was 24 years old.

Mr Montalto denied the allegations, but the tribunal accepted the "consistent" and believable evidence from five women accusers, a male student in his ethics class, a course coordinator and another staff member.

Most of the allegations were made by a student who said she was bombarded with inappropriate texts and calls in 2014.

He sent her an intimate photo and solicited photos from her, asked her to write an explicit story about her and another female student, and made her delete her text and call history with him.

"Mr Montalto ultimately threatened that he would fail me if I did not agree to his requests, though I cannot recall the exact words that he used," she told the tribunal in September.

"I understood this to be a genuine possibility and that it was within his power to do so. I felt extremely anxious about the prospect of having to repeat the unit and risk having Mr Montalto as my lecturer again, and this was the predominant reason that I continued to communicate with Mr Montalto and generally did as he asked."

He told the tribunal she was in a different tutorial and he couldn't influence her marks, but VCAT found that he had the perceived power to do so.

Mr Montalto was this week stood down from another university, RMIT, which is now investigating whether any of its students have been exploited.

The main complainant had visited Mr Montalto in 2014 at an RMIT office to borrow a textbook. Mr Montalto then placed his hand at the top of her thigh and said he wanted "to bend you over and f--- you".

"In light of the [VCAT] decision, we recognise that misconduct towards students from another tertiary college may have occurred at an RMIT location," an RMIT spokeswoman said in a statement.

"The safety and wellbeing of our students is our absolute priority and we will therefore be standing down the individual from any future casual employment at RMIT and undertaking a full and thorough investigation."

At end of trimester drinks in August 2014, Mr Montalto was found to have exposed his erect penis to one of the women, pinned her against a roller door, and put his hand down her bra while she waited for her mother to pick her up.

Earlier that month at ethics drinks at the Lion Hotel in Melbourne's CBD, he had asked one student if she had a boyfriend, if she was a virgin, and which sex positions she liked.

Mr Montalto was also accused of licking one woman's neck at the ethics drinks.

"In our view his behaviour was deliberate, predatory and opportunistic," the judgement said.

The case was brought by the Psychology Board of Australia because Mr Montalto was a provisional psychologist at the time of the allegations.

The tribunal found he was not a fit and proper person to be a provisional psychologist, even though he wasn't teacher or practising at the time.

He was found guilty of professional misconduct.

VCAT will hand down a penalty in December.
